Which statement describes a spot fire?

• A. A spot fire is a fire caused by embers landing ahead of a main fire.
• B. A spot fire is a torch that burns a tree.
• C. A spot fire is a fire that occurs on the surface of water.
• D. A spot fire is a surface fire.

Answer: (A)

Spot fires form when embers carried by the wind land ahead of the main fire and start new flames in unburned fuels. This forward ignition creates separate fires that can run ahead of the primary fire line, complicating suppression efforts. The other statements don’t describe this forward-ignition process: a torch burning a tree is about one tree catching fire (torching) rather than embers starting a new fire in front of the main front; a fire on the surface of water isn’t the typical spot-fire mechanism; and a surface fire is a general type of ground-fuel fire, not specifically the result of embers landing ahead of the main fire.
